LOOM FOR WEAVING TUFTED FABRICS.

SPECIFICATION forming part of Letters Patent No. 343,112, dated June 1,1886.

Application filed October 7, 1885. Serial No. 179,213.

To aZZ whom it may concern:

Be it known that we, GEORGE ORoMrroN and HORACE WVYMAN, of WVorcester,county of WVorcester, and State of Massachusetts, have invented anImprovementin Looms for Weaving Tufted Fabrics, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

This invention relates to looms of that class adapted for the productionof tufted fabricssuch, for instance,as moquette carpets-the object oftheinvention being to improve and simplify the means for controlling thetuft-yarns, in order that the same may be taken directly fromindependent spools or bobbins, one for each tuft-yarn, thus obviatingthe beaming of yarns of different colors on separate warpbeams, one foreach transverse row of tufts, and also to dispense with the chains andmoving devices therefor, as heretofore usually employed.

The invention herein contained consists, essentially, in a series ofhorizontally-sliding tuft-yarn presenting carriages arranged side byside, and means to move the said carriages varying distancesin thedirection of the length of the warp-threads, the said carriages having aseries of openings or eyes arranged therein, one behind the other, inthe direction of the length of the warp, combined with tuftyarn-seizingdevices to pass up between the warp-threads and seize the ends of thosetuftyarns depending from the lower sides of the said carriagcs,which, bythe movement of the carriages, are left in operative positionimmediately above the said tuft-yarn-seizing devices, the latter actingto seize and draw the said tuft-yarns directly between the warpthreads,as will be described. 7

In another application, No. 136,604, filed by us July 2, 1884, we haveshown a series of carriages adapted to be moved in the direction of thelength of the warp-threads, each carriage having a series of independentmovable tuft-yarn carriers or needles, each supplied with yarn from aseparate spool or bobbin, each tuft-yarn carrier or needle being undercontrol of a pattern-surface.

United States Patent No. 39,759, dated Sep- (No model.)

tember' 1, 1863, shows and describes a loom containing pinchers to taketuft-yarns from spools carried by chains, each spool having the yarnswound thereon in the order of the colors of some one transverse row oftufts to be made, there being one such spool for each different row oftufts to be produced.

The loom herein to be described contains parts of each of the loomsreferred to, and in combining them operatively we have considered itunnecessary to show but few of the parts of each of the said looms, theparts which are not shown being common to the looms referred to.

Figure 1 is a partial section of a loom embodying our invention, thecarriage shown being partially broken out to show the tuftyarn groovesor passages therein, the creelframe holding the tuft-yarn spools beingomitted. Fig. 2 is a broken partial front elevation thereof, part of thecards of the pattern chain or surfaceof the Jacquard apparatus and theupper barrels being omitted, as well as the parts belov the breast-beam.Fig. 3 is a detail to be referred to. Fig. 4 shows a modified form ofcarriage; and Fig. 5, a separate view of part of the creel and a numberof tuft-yarn spools, there being a spool for each tuft-yarn used.

The loom-frame d, the pinchers or nippers 2', arm of, arm a lever Z,adjustable rod 0, shaft q, and cams m and a are substantially the samein construction and operation as the parts marked by like letters in theUnited States Patent No. 39,759, dated September 1, 1863, and inpractice the said nippers t will be opened and closed and operated insubstantially the manner described in said patent, to engage thetuft-yarns t and pull them into the shed of the warp-threads to formtufts.

The loom herein described may have shedforming mechanism substantiallythe same as in the said patent; but we have herein considered itunnecessary to show the shed-form ing mechanism; nor have we consideredit necessary to show all the parts which actuate the nippers 73, nor allthe parts which co-op'erate with the said nippers when taking thetuft-yarns and making them into tuft-loops, for all the said parts formanipulating the 100 tu ft-yarns may be found fully described in thesaid patented loom.

Desiring to dispense with the long chains and series of spools havingthe tuft-yarns wound thereon in the order of colors appearing in eachtransverse row of tufts, we have in their place arranged side by side aseries of tuft-yar11- presenting carriages, E, and have placed the saidcarriages in grooves of rests or bars 109, extended from side to side ofthe loom, the said carriages being free to be slid or moved horizontallybackward away from the breast-beam and in the direction of the length ofthe warp by the action of a patternsurface, to be described, it, asherein shown, acting upon one or the other of a series of projections, 23 4 5 6, extended horizontally from the end of each carriage, as shownbest in Figs. 1 and 4. Each carriage has a stop, 7, which is normallykept pressed against one of the bars or rests 109 by a spring, 8,connected at one end with a pin, 9, attached to the carriage E, and atits other end with a rod, 10, held at each end by a bracket, as at 15,secured to the frame 12, which supports the shaft 14 of the hollowhexagonal barrel 13, preferably com posed of metal plates joi ned tohead-pieces. Each of the plates composing the barrel 13 is provided, asherein shown, with five rows of holes (see Figs. 1 and 2) to correspondwith the five projections 2 to 6, inclusive, of each carriage, therebeing as many holes in each longitudinal row of holes as there arecarriages E in the series from side to side of the loom, there being asmany carriages as there are tufts in each transverse row of tufts. Butone end of the shaft 14 is shown in the drawings, as the other is likeit.

The shaft 14 shown in the drawings is provided with a bevel-gear, 16,and with a wheel, 17, having pins 18, which are engaged by a pawl, 19,pivoted at 21 on a standard, 20, attached to the loom-frame near thebreastbeam 22. The bevel-gear 16 engages a bevelgear, 23, on the uprightshaft 24, held in bearings attached to the frame 12. The upper end ofthe shaft 24 has a bevel -gear, 25, which engages a bevel gear, 26, on ashaft, 27, having upon it a barrel, 28. The shaft 27 has a toothedwheel, 29*, which en gages a toothed wheel, 30, on a shaft, 31, providedwith a third barrel, 32, and below this barrel is a suitable cradle, 33,to support in usual manner the chain of pattern-cards 29, of usualconstruction, the said barrels being operated to move the said chain ofpattern-cards interinittingly. The gears 29 and 30 are attached to theshafts 27 and 31 justinside ofthe rigid overhanging part a of theloom-frame, and are omitted in Fig. 2. The pattern-cards 29, connectedin the proper order, and, together with the barrel 13, constituting thepattern-surface, are each provided with, holes, some of which coincidewith those of the said barrel; but each pattern-card serves to close oneor more of the holes of each vertical row of holes in the barrel, theparticular hole which is so closed depending upon the exigencies of thepattern in the fabric being woven.

' Fig. 2 shows a part of but one of the cards perforated for nsein usualmanner. The frame 12 is vibrated or swung backward and forward atregular intervals by links 35, attached in practice to the journals ofthe shaft 14 at each end of the barrel 13, and to the levers 36 on ashaft, 37, one of said levers having an arm, 37*, connected by a link,38, with a lever, 39, pivoted at 60, and acted upon by a cam, 62. (Shownin dotted lines, Fig. 1, on the shaft q.) As the barrel is swung outwardby the devices deseribed, the hook ed pawl 19 in engagement with a pin,18, of the disk 17, attached thereto effects the partial rotation of thesaid barrel, bringing a new card, properly perforated,according to thepattern, in position with relation to the projections 2 3 4 5 6.

The horizontally-movable carriages E are provided with openings orpassages for the reception of the tuft-yarns t, which latter are drawnthrough the said passages. one behind the other, in the direction of thelength of the carriages, leaving the free ends of the tuftyarns tdepending singly side by side, but not touching each other, from thelower under side of the carriages, in which condition the tuftyarns tare retained frictional] y, to be caught by the nippers i or other usualequivalent device employed to grasp the tuft-yarns t and pull them fromthe recesses or openingsin the carriages to form from them the tufts toappear in the fabric. Preferably the carriages will have small nipplesor projections at their under sides, as in Fig. 1; but, if desired, thecarriages may be made from sheet inetal bent into V shape andperforated, as in Fig. 4, which shows alongitudinal and a cross sectionof a modified form of carriage with tuft-yarns therein, the upper partor edge of the carriage being pinched together to produce sufficientfriction on the tuft-yarns to keep them from slipping back in thecarriages.

The passages for the tuft-yarns made in the carriages (shown in Fig. 1)will in practice be of such diameter as to receive the yarnssufficiently snug to produce the required tension and prevent the yarnsfrom slipping back.

The tuft-yarns t, taken from spools'B on a creel or frame, B Bsubstantially as shown in Fig. 5, and also in our applicationhereinbefore referred to, are led through guides in a guide-board, 95,supported from the frame a", the saidguide-board and guides enablingthetuft-yarns to be directed from ahorizontal into a vertical plane, theguide-holes being so 10- catedand the board so placed that the tuftyarnsare led into the passages of the carriages one behind the other, theguide-board preventing the interference of the separate yarns going notonly to each carriage, but to all the carriages. After the formation ofeach row of tufts the barrel 13 and pattern-cards are moved to the left,viewing Fig. 1, by the cam 62 and parts actuated thereby, as beforedescribed, and the barrel is turned one step,

IIO

bringing a new card in working position. WVhile a new card is beingbrought into working position, the springs 8 act to draw all thecarriages toward the breast-beam with the stops 7 againstathe rest 109,and thereafter the pattern-card is moved to act against the projectionsof the carriages, moving them different distances, according to whichprojection 2 to 6 is struck by the card, and the carriages having beendistributed by the pattern-sun face the piuchers or nippers t are raisedbetween the warp-threads and opened or made to engage the tuft-yarns, asprovided for in United States Patent No. 39,759, hereinbefore referredto, the pinehers i herein shown being the same as contained therein,anddesignated by like term and letter.

WVe do not intend or desire to limit our invent-ion to the exactconstruction of pinchers shown, as we may employ other well-known formsof pinchcrs, which rise from below the warp to seize the tuft-yarns andform loops.

The projections 2 to 6 are of different lengths, their difference beingsubstantially equal to the distance from center to center of thedifferent tuft-yarn carriers. When the projection 2 is struck by theface of a card moved against it by the barrel as the latter is movedbackward from the breast-beam, and the projections 3 to 6, inclusive,enter holes made in the card, and thence pass into the hollow barrel 13,the carriage will be moved for only such distance as to place thetuft-yarn v t second from the right in Fig. 1 in position to be seizedor taken by the nippers i.

In Fig. 1 the card is shown as having struck the projection 3, which isof a length to insure the placing of the third tuft-yarn 15 from theright of Fig. l in position to be taken by the nippers.

If the hole in the barrel 13 opposite the longest projection, 6, iscovered by a part of the card, and the latter is thus made to strike theprojection 6, the carriage E will receive its greatest movement,and willbe placed in such position with relation to the nippers i as to placethe tuft-yarn t at the left-hand end of the carriage in position to betaken by the nippers.

The positions of the holes of each row of vertical holes in thepatterncard vary according to the particular color of the tuft which it isdesired that each carriage of the series of carriages shall contributeto the next transverse row of tufts to be made, and consequently thecarriages will be moved over different distances at each movement of thepattern-surface toward them, the distance depending upon which of thetuft-yarns of each carriage is to be left in operative position to haveits yarn caught by the nippers i.

We denominate as the row of effective tuftyarns those which are left ina transverse row, ready to be taken by the nippers or pinchers and bedrawn between the usual warp-yarns to produce a transverse row of tufts.After the completion of each row of tufts the carriages are all moved totheir full extent toward the breast-beani,ready to be again movedvarying distances for the next row of tufts, and so on according to theparticular colored yarn that each of the carriages is next to contributeto the effective row of tuft-yarns. The ends of the tuft-yarns,haviugbeen drawn down between the warp-threads,are then turned up above thewarps, as in thevPatent No. 39,759, and the tuft-yarns will then be cutoff at the proper distance above the closed shed to form tufts of theproper length.

We have not considered it necessary to show the tuft-cutting mechanism,as it may be of usual constructionsuch, for instance, as in UnitedStates Patent No. 233,290. V

The cam on strikes the roller at the end of the lever Ve do not desireto limit our invention to the exact form of patternsurface toautomatically move the carriages horizontally over varying distancespreparatory to forming each row of tufts in the fabric being woven, andinstead of the pattern-cards shown we may employ any other well-knownequivalentpattern-surface.

WVe do not herein claim a series of carriages containing tuft-yarncarriers or needles which are moved independently 'in the carriages, forsuch devices are shown and claimed in our application Serial No.136,604; nor do we herein claim a series of carriages each havingaseriesof tuft-yarn carriers or needles-which are acted upon and moved by thesaid carriages, as such devices form the subject-matter of anotherapplication made by us, Serial No. 142,487, filed September 8, 1884.

In Fig. 5 we have shown by itself the upright B, and the projecting armsB, eonsti tuting a creel for the reception of the spools B B, one foreach tuft-yarn 25 used, the said tuft-yarns being carried from the saidspools through holes in the guide-plate 95, and thence to the carriages,the free ends of the said yarns depending from the said carriages.

We claim l. A series of horizontally sliding or moving carriagesarranged side by side, and provided with passages arranged one behindthe other in the direction of the length of the warp for the receptionof the tuft-yarns, whereby the latter depend vertically from the lowerside of the said carriages, and means, substantially as described, tomove the said carriages for varying distances in the direction of thelength of the warp threads, combined with pinchers or nippers,substantially as described, to seize the ends of the tuft-yarnsleftdepending from the carriages when left in operative position above them,and with means to operate the said pinchers or nippers, substantially asdescribed.

2. A series of sliding carriages arranged across the loom side by sideslightly above the level of the breast -beam, and provided, eachcarriage, with a series of passages for the reception, one behind theother, of a series of IIS tuft-yarns, and means, substantially asdescribed, to automatically move the said carriages over varyingdistances to place the desired tuft-yarn of each carriage in what is tobe the effective row of tuft-yarns, combined with guides to receive anddirect the said tuftyarns to the passages of the carriages,substantially as described.

3. A series of tuft-yarn carriages provided with passages for thereception of several tuft yarns, one behind the other, in the directionof the length of the warps, and having projections of difl'erentlengths, combined with a pattern card or surface and means to'move it,to operate substantially as described.

4. The series of tuft-yarn carriages provided to moving them for theselection of each effective row of tufts, substantially as described.

5. A series of carriages arranged side by side across the loom, andprovided each with a series of tuft-yarn passages. one behind the other,and a creel and spools to hold each but one of the tuft-yarns led to thesaid carriages, and a series of guides for the tuft-yarns between thespools and carriages, combined with means, substantially as described,to automatically operate the tnft-yarn carriages for differentdistances, according to which particular tuft-yarn of each carriage isnext to be employed in the next row of tufts.

In testimony whereof we have signed our names to this specification inthe presence of 0 two subscribing witnesses.
